Does anyone use this stuff? I got some for free from a relative. I know it will shear back to a 30wt fast (under 3,000 miles) I did a search and only found a couple of hits on the castrol 10w-40 I was just wondering if anyone has used it/like it. Thanks

I use this GTX 10w-40 stuff, have been using it for 15-20 years, no complains, plenty of praise for Castrol. I put in a UOA for Castrol GTX 10w-40 about 2 months ago. Search "Suzuki Sidekick.... 3,300 miles OCI" It performs pretty well under stress. I have run engines after catastrophic cooling system failure, 'till all the GTX boiled off. No shoulder on that highway. Engine still A-OK after all that. No ring sticking too, despite what many people say about "too much V.I. improver" in 10w-40 oils.
Your GTX 10w-40 will be good for 4,000 miles OCI. You will not have any problems with Castrol GTX.
